Summary

This study compares two ways to soften and open the cervix before a second-trimester abortion procedure called dilation and evacuation (D&E). One method uses a small balloon catheter placed through the cervix for a few hours; the other uses synthetic rods that swell as they absorb moisture. The goal is to see if the balloon method works as well as the dilators, focusing on how long the procedure takes, pain, and satisfaction.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Transcervical single-balloon catheter (Foley catheter) and synthetic osmotic dilators (Dilapan-S)
What this could lead to
If the balloon catheter works as well as osmotic dilators, it could offer a simpler, more comfortable option for cervical preparation before a second-trimester abortion.
What could go wrong
This is a small, early-stage trial with only 32 participants, so results may not apply to everyone. The balloon method might not prepare the cervix as effectively, leading to longer or more complicated procedures.
